Today’s LiveWire Spotlight evaluates a NERC Modeling Notification which provides recommendations and guidance concerning the testing of MOD-026-1 and MOD-027-1 dynamic models.  The document is intended to assist Transmission Planners confirm that the GO-validated models integrate properly into the wide-area data set.

GOs are deploying high-speed digital control systems at a rapid rate – driving the need for more accurate dynamic models and data recorders.  FERC may take action (i.e.; new standards) if they see that MOD-026/027 validations are not facilitating that goal.
